A tap is Homebrew-speak for a Git repository containing additional formulae.
Homebrew has the capability to add (and remove) multiple taps to your local installation with the brew tap and brew untap commands; run man brew in your terminal for usage information.
Your taps are Git repositories located at $(brew --repository)/Library/Taps. As a normal user, you usually won't see homebrew/core here anymore and that's OK - normal usage is via the JSON API.
The taps and forks below are third-party repositories that are not maintained, reviewed or trusted by Homebrew. Tapping or installing from them runs their code with your user's privileges, so only add ones you trust. See Tap Trust for how to trust only the specific formula, cask or command you need and Software Supply Chain Security for why this matters.
DomT4/autoupdate: An external command to automatically run brew update (and optionally brew upgrade or brew cleanup) in the background with launchd.
homebrew-ffmpeg/ffmpeg: A tap for FFmpeg with additional options, including nonfree additions.
